TANK VEHICLE UNDERFRAME Filed June 13. 1931 2 Sheets-Sheet 2 Patented Nov. 22, 1932 JAMES C. TEAVILLA,,JR=,.OF PHILADELPHIA, PENNSYLVANIA, Assienon 'roeEnEnAL srnnneAsrmes CORPORATION, on enAni-zrn orra, rumors, A CORPORATION or DELAWARE TANK VEHICLE UNDERFBAME Application filed June 13,

This invention relates to railway rolling stock and consists in a novel vehicle underframeand particularly the end construction thereof adjacent the draft gear. In the usual 'wate'r bottom ten'der under-frame, for example, a double'draw bar pocket is formed beneath the "front endsill and extends rear- I wardlyfthereof and the walls of the pocket form a portion ofithe wall of the water con- Itaining compartment of the underfraine.

If any'le'alis-develop in this oortion of the tank wall, they must be'repaired through the draw bar pockets. These pockets are compa'rativelynarrow and, consequently, access to-the tank w-all'throughthem is dihicult.

he main object of the present invention is to construct a waterbottom'underframe in whic'lithe walls of the/draw bar pockets form no part of the tank walland in which the portions of" the tank wall adjacent the draw barpockets are readily accessible for the purpose of repairing leaks.

These'objects and others are attained in the structure illustrated'in the accompanying drawings in which ll igure 1 is a top View of a" portion of a tender frame embodying the'inventiony Figure 2 is a sideview of the same;

Figure 3 isa' vertical longitudinal section 'taken'on the longitudinalcenter lineof Figure Land-shows a portion of: the floor of the coal v bunker and of: the front wall of the water: tank beneath the bunker.

Figure f is a front View of the structure shown inFigure v1.

Figure 5 is a verticaltransverse section taken on'the line.5.5 of Figure 1.

I illustratemyinvention as applied toa one piece Waterbottom tender 3 underframe which includes sidesills 1, center sills ,2 intermediate sills 3, transoms 4c, and an end sill 5. A horizontalweb 15 having perforations lfia to facilitate casting, extends between the tops of the center sills. A pocket Gfor a buffing device 7- is located forwardly of the center of the end sill 5, and members forminga double draw bar pocket 8, 9 dependfroln the bottom web 1'0'of the underframe castin'gand exte'nd' rearwardly of sill 5.

the rear portion of the draw bar pockets from web 10.

Horizontalbottom web 10 and the 'sidean'd end sills 1 and 5, respectively; are preferably cast integral and are imperforate whereby the entire casting serves as a tank bottom member'to which tank side and end sheets 21 and 22 are secur d. An opening 11 is'provided in weblO for connection with a conduit leading to the boiler of the engine.

Immediately above the draft pockets 8, 9, web 10 is recessed as indicated at 10a and up* right webs 12 and 13 extend around recess 10a and with end sill 5' form a box shape member which'serves to exclude water from the portion of the casting immediately a'djacent' the draft pockets. Horizontal and vertical draw'bar pocketwallsBoo 18, and 19 are spaced from webs 12 and 13 of the tanlc The front portionof the coal bunker floor 16 is supported above the draw bar pockets upon uprightplates 17 and'l8 which are welded to top web in alignment with webs 121and 18, respectively, and which form a recess R in the tank front wall. Access maybe readily'had through this recess and through opening A in top web 15 to the portions of the water compartment of the underframe immediately adjacentthe draw bar pockets.

In practice the invention does not materially decrease the capacity of the vehicle from that of the usual construction since the water containing portions ofth-e under fr ame extend forwardly oneach side of the pockets to the end sill. Obviously, the necessity of gaining access through the draw bar pockets 'for'the'purpose of caulkingleaks is'elimina'ted' as the tank walls at all points are spaced substantially from the draw bar pocket wallsand underframe Webs 12 and 13 are easily accessible from thetop through opening 1 1 and the recessed front sheet of the superstructure, or from the bottom on either side of'rib through opening 10a.

While I have illustrated the invention as applied to a water-bottom tender underframe, the principles thereof might be readily embodied in any other type of underframe in which it is desired to separate a fluid chamber or passage from an adjacent draft pocket. The invention, of course, is not limited to the exact details illustrated, but may be modified in various other ways, as will be apparent to those skilled in the art, without departing from the spirit thereof, and I contemplate the exclusive use of all such modifications as come within the scope of my claims.

I claim:

1. In a railway vehicle undertrame, a draw bar pocket, and underframe elements forming walls, a fluid compartment extending around the sides and rear of said pocket, the adjacent walls of said pocket and compartment being spaced apart to provide access between them to said compartment walls for inspection and repair purposes.

2. In a railway vehicle underframe, a draw bar pocket, and a fluid compartment wall formed in the nnderframe at the rear of said pocket, the adjacentwalls of said pocket and compartment being spaced apart to provide access between them for inspection and repair purposes.

3. In a railway vehicle underframe, a fluid compartment formed in part by underframe elements, and a draw bar pocket extending inwardly at the lower portion of an end of said undertrame,v said compartment extending on opposite sides of said pocket and the walls of said pocket being spaced from the walls of said compartment a sufficient distance to permit access from outside said pocket to the portion of said compartment wall adjacent said pocket.

at. In a railway vehicle undertrame, a draw bar pocket having vertical and horizontal walls, a liquid compartment formed in part by underframe elements at the rear of said pocket and extending forwardly at the sides of said pocket and having vertical end walls and a substantially horizontal bottom web plate, said draw bar pocket walls being I spaced from said liquid compartment walls and web plate so as to provide access to Said latter walls and web plate.

5. In a railway vehicle underframe, an end sill, a draw bar pocket having vertical and horizontal walls extending below and rearwardly of said end sill, and a liquid compartment having vertical end walls and a bottom web plate formed by underframe elements, said draw bar pocket walls being spaced from said liquid compartment walls and web plate to provide access to said latter mentioned walls and web plate.

6. In a railway vehicle und-erframe, an end sill, a draw bar pocket extending inwardly beneath said sill, and a fluid compartment wall formed by underframe elements and extending inwardly from said sill on at least one side of said pocket, all of the walls of said pocket being spaced from the walls of said compartment.

7. In a railway vehicle underframe, an end sill, an imperforate underframe bottom plate serving as a wall for a fluid compartment, a recess in said plate adjacent said sill, upright webs extending around said recess and serving to exclude fluid from said recess, and a draft pocket extending from said sill into said recess and having horizontal and vertical walls, said walls being spaced from said webs and bottom plate.

8. In a railway vehicle underframe, an end sill, an imperforate bottom plate serving as a wall for a fluid compartment, a recess in said plate adjacent said sill, upright webs extending around said recess and serving to exclude fluid from said recess, a draft pocket extending from said sill into said recess and including horizontal and vertical walls, said walls being spaced from said webs and bottom plate, and a rib supporting the inner end of said pocket from said plate.

9. In a railway vehicle underframe, an end sill, a draw bar pocket extending inwardly beneath said sill and having vertical and horizontal walls, and a fluid compartment extending on opposite sides of said pocket and including upright end members, each spaced from the walls of said pocket, the top of the underframe between said end sill and said members being open to permit access to said members.

10.

11. In a railway tank vehicle underframe, an end sill, a draw bar pocket extending inwardly beneath said sill, a fluid compartment extending on opposite sides of said pocket and including upright end members, each spaced from the walls of said pocket, the top of the underframe between said end sill and said members being open, and additional upright plates forming an open pocket above said vertical members, said upright plates constituting portions of the tank wall.

12. In a railway tank vehicle underframe, an end sill, a draw bar pocket extending inwardly beneath said sill, a fluid compartment extending on opposite sides of said pocket and including upright end members, each spaced from the walls of said pocket, the top of the underframe between said end sill and said members being open, additional upright plates forming an open pocket above said upright members and constituting portions of the tank wall, and a coal bunker mounted on said additional plates.

13. In a railway Vehicle, an underframe including a fluid compartment, an end sill, and a draw bar pocket extending inwardly beneath said sill, and super-structure including tank side and front sheets secured to said underframe and a coal bunker, said front sheets including a depressed part above said draw bar pocket, said part being spaced from said pocket and co-operating with said bunker to exclude fluid from the walls of said pocket, and also forming a passage above said end sill through which access may be had to the portions of said underframe adjacent said drawbar pocket.

In testimony whereof I hereunto aflix my signature this 6th day of June, 1931.
